Convert Access Database To SQL Server?

I've created an application using ASP.NET with Access DB, now I found somee.com who support only SQL Server DBs, so Now I must convert my Access DB to SQL Server DB.

Is there any tool who can do the trick ?

This is some code I'm using in my web application :

Public Shared Function conecter() As OleDbConnection
Dim MyConnexion As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data source=" & System.AppDomain.CurrentDomain.BaseDirectory & "/Learning.mdb")
MyConnexion.Open()
Return MyConnexion
End Function
Public Shared Function lecture(ByVal requete As String) As OleDbDataReader
Dim Mycommand As OleDbCommand = conecter().CreateCommand()
Mycommand.CommandText = requete
Dim myReader As OleDbDataReader = Mycommand.ExecuteReader()
Return myReader
End Function

In this case, If I convert my database I must change the OleDbConnexion and other things or I can just leave them like that ?
